If I 'ruled the world', my current thinking is that the World Puzzle week should be organised roughly along the lines of: -Monday: World Sudoku Championship, 3 hours max (not necessarily in one go!) of classic Sudokus; World Tapa Championship, 3 hours max (not necessarily in one go!) of classic Tap...

Sudoku is the king of logic puzzles in the 21st century and WPC deserved his younger brother - WSC, I think we all agree about that. Yes, many debatable puzzles appeared in past WSC's so I support this discussion to determine what can go in future WSC and what can not. However, I think this is a pla...

It consists of one round and three puzzles which are scored separately. All necessary details will be announced in the together with the puzzles on Friday, N...

Congratulation James, fantastic performance! Interesting thoughts about the last puzzle. You described openings in the right way. Maybe in this most important solving phase well-known "trial and error" method is the fastest. I might add if you try to paint in black R7C1-R7C2, you will get full 5th a...

Since last year 24-Hour Puzzle Championship did not take place, I was hoping that this year will be at least two such events.

Yes, I missed that rule .

I think Anurag has right. Puzzle 1.3 goes to double solution in top right corner. Number 8 can be reached in two ways, but the solution key is the same. I noticed this during the solving and lost some time here.
